BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention relates to a tea bag, and in particular, an improved structure of a tea bag having a corrugated bag body being made from porous and hydrophilic paper material.

[0003] (b) Description of the Prior Art

[0004] One problem with presently known tea bags is that the bag body occasionally comes apart when the tea is being made, thereby releasing some of the tealeaves from the bag. The defects of the bag body generally results from a sudden build-up pressure of air in the tea bag due to heating of the air when hot water is poured into a cup containing the tea bay, usually accompanied by a mechanical force resulting from impingement of a water stream on the tea bag. Another problem with conventional tea bags involves release of tealeaves from the front surface of the bag body, again due to an air pressure increase and the force of a water stream.

[0005] Conventional tea bag, as shown in FIG. 1, is provided with a bag body 10 containing appropriate amount of tealeaves and the bag body 10 is then covered and sealed. The top edge of the bag body 10 is then connected with a cotton thread 11 at one end. The other end of the cotton thread 11 is connected to a tab 12 for the holding of the tea bag by the user and facilitating the withdrawing of the tea bag from a cup.

[0006] The conventional tea bag has a very limited space for the tealeaves to be extended when the tealeaves are brewed within a cup of hot water. Besides, when a second time adding water to the teacup, the tea bag will float on the surface of the water and occasionally, the tab falls into the cup.

[0007] In view of the above, it is an object of the present invention to provide an improved structure of a tea bag, which mitigates the above drawbacks.

SUMMARY OF THE INVENTION

[0008] Accordingly, it is an object of the present invention to provide an improved structure of a tea bag, wherein the bag body is corrugated which can be extended and the bag body is made from higher porosity and hydrophilic paper, and the top face of the bag body is a first porous face with loosen pores, and the center of the bag body is a second porous face with further loosen pores, thereby, the bag body provides an effective way of brewing tea.

[0009] A further object of the present invention is to provide an improved structure of a tea bag, wherein the top face of the bag body is provided with only a first porous face, facilitating the fabricating process of the tea bag.

[0010] Still another object of the present invention is to provide an improved structure of a tea bag, wherein the configuration of the bag body is a square base body, hexagonal shape base body and an octagonal shape base body so as to fully utilize the capacity of the bag body.

[0011] The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

[0012] Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0019] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0020] Referring to FIGS. 2 and 3, there is shown a tea bag structure having a bag body 10. The teabag 1 is provided with a corrugated bag body 10 which can be extended. If the tea bag 1 is not in use, the tea bag 1 can be pressed to form a flat shape facilitating vacuum packing. When using the tea bag 1, the bag body 10 can be stretched or extended. In accordance with the present invention, the bag body 10 contains appropriate amount of tealeaves and the bag body 10 is made from porous and hydrophilic paper material. The top face of the bag body 10 is a first porous face 13 with loosen pores, and the center of the bag body 10 is a second porous face 14 with loosen pores. The center of top face of the bag body 10 is provided with a cotton thread 11 connected to a tab 12.

[0021] The first and the second porous face 13, 14 at the top face of the bag body 10 can be simplified to form only one first porous face 13, as shown in FIG. 4. This will provide the similar convenience in adding hot water to brew tea.

[0022] Referring to FIG. 5, in application of the tea bag 1, the tea bag 1 is stretched and is placed within a cup 2. Next an appropriate amount of hot water is added and the tealeaves are provided with sufficient space for expansion. Due to the fact that the top face of the bag body 10 of the tea bag 1 is provided with the first and the second porous face 13, 14, the adding of water to the tea bag 1 is inconvenient. In particular, when a second time or subsequent steps to add water to the tea bag. This will avoid the possibility of tea bag 1 floating on water as a result of air within the tea bag 1. Due to the fact that the volume of the tea bag 1 is comparable to the capacity of the teacup, the cotton thread 11 and the tab 12 will not fall into the cup 2.

[0023] Referring to FIGS. 6A, 6B and 6C, the configuration of the bag body 10 of the tea bag 1, other than cylindrical shape body, can be a square-base body, a hexagonal shape base body, and an octagonal shape base body.

[0024] While the invention has been described with respect to preferred embodiment, it will be clear to those skilled in the art that modifications and improvements may be made to the invention without departing from the spirit and scope of the invention. Therefore, the invention is not to be limited by the specific illustrative embodiment, but only by the scope of the appended claims.

[0025] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0026] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
